Timing of Low-Dose Aspirin Discontinuation for chronic subdural hematoma

Anticoagulant and antiplatelets therapies increase the risk for both occurrence and chronic subdural hematoma recurrence ^{1) 2) 3) 4) 5) 6)}

These drugs are generally used for first and secondary prevention of thrombotic-embolic events, especially in elderly people. Guidelines recommend 5-7 days of acetylsalicylic acid (ASA) suspension to perform a safer surgery ^{7) 8)}.

Even if the antiplatelet effect would be rationally associated with an increased morbidity and mortality in patients with a CSDH, this is not uniquely demonstrated in literature. Only few studies assessed the risks of antiplatelets in the surgical management of CSDHs
